Information processing apparatus, information processing method, and computer-readable recording medium

An information processing method comprising:

• acquiring time-series observation data for each measurement point of an object, the time-series observation data being generated by emission of radio waves from a flying object to the object;
• and
• selecting a specific measurement point by using temporal coherence used for estimation of a parameter for modeling the observation data for each measurement point, and calculating the parameter and a residual phase component of an unselected measurement point by using the parameter and the residual phase component generated at the time of the modeling at the selected specific measurement point.

A non-transitory computer-readable recording medium recording a program for causing a computer to:

• acquire time-series observation data for each measurement point of an object, the time-series observation data being generated by emission of radio waves from a flying object to the object;
• and
• select a specific measurement point by using temporal coherence used for estimation of a parameter for modeling the observation data for each measurement point, and calculate the parameter and a residual phase component of an unselected measurement point by using the parameter and the residual phase component generated at the time of the modeling at the selected specific measurement point.
